LTE and WLAN fair co-existence in unlicensed bands

Abstract

With the growing demand for wireless communication, there is an increasing need for efficient and reliable sharing of unlicensed frequency bands. Due to the difficulties involved in sharing the same frequency spectrum, the coexistence between LTE and WLAN over unlicensed bands has emerged as a significant area of research. This paper presents a study on the LTE co-existence with WLAN in unlicensed spectrum using NS-3. Our paper comes up with a hybrid network analyzer that implements Maximum throughput scheduling and exponential rule algorithm along with cat4 LAA LBT for achieving fair co-existence. The performance of these mechanisms is evaluated in terms of throughput, latency and fairness. The study also includes an investigation of the impact of various network parameters such as network topology, traffic load, and interference. The outcomes demonstrate that the suggested hybrid network analyzer can effectively manage the LTE, and WLAN co- existence in unlicensed bands, providing high throughput and fair resource allocation.
